Abstract

The system is used in aircraft engineering, in particular in helicopter making. It builds a reliable barrier against the formation of a "vortex ring" and has anti-icing effect. It consists of propeller blades (10) suspended on a propeller shaft (1). A tube (12) for gases under pressure fed by compressor (7) is passed inside each blade (10). End (15) of tube (12) reaches the external end (16) of propeller blade (10) where at least one nozzle (17) is mounted and to outlet (27) of blade (10) where there is a nozzle (28) at the end of each tube (16). Gas-fluid barriers (25 & 29) are formed by the flowing out of gases under pressure which do not allow the formation of a lateral turbulence and "vortical ring" above blade (10).
